MOUNT FOR SPINDLES 0F SPINNING OR TWISTING MACHINES.

Application filed November To all whom it may concern:

Be it known that l, HERBERT G. BEEDE, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Mounts for Spindles of Spinning or Twisting Machines, of which the following is a specification.

This invention relates to improved means for mounting spindles of the floating or flexible type, and it consists essentially of a spindle-blade provided with a driving whirl,

a non-revoluble bolster having said blade freely revoluble therein, a stationary hollow base having its upper portion recessed or chambered to receive and support the bolster, said base portion being enveloped by the driving-whirl, and a ball-bearing having its inner race rigidly fixed to the blade and the outer race seated in said bolster recess and capable of limited :triotional rotary movement therein, constructed and arranged whereby the ball-bearing is normally submerged in the oil or lubricant. By means of my improved construction of spindle mounting the spindle is practically self-alining in that it automatically adapts itself to varying gyratoiy conditions of speed, load and band pull; the weight or thrust of the revolving parts longitudinally is borne by the positioned ball-bearing, the latter at the same time also neutralizing the lateral or radial pulling force of the band. In the present improvement the bolster is extended and enlarged so that the ball bearing is positioned at a point practically opposite or midway of the whirl. As thus constructed the device is rendered more sensitive in correcting variations in the speed, &c., of the spindle. The oil reservoir extends above the top of the bolster thereby ensuring the submergence of the ball-bearing in the lubricant. The spindle mount is simple, not liable to become accidentally inoperative, and the cost of manufacture is materially reduced.

Tn the accompanying sheet of drawings Figure l is a longitudinal sectional view, taken substantially through. the center of the device, and Fig. 2 is a side elevation of the bolster and a. portion of the blade showin a slightly modified form; the upper an lower end portions of the bolster, in-

cluding the ball-bearing, being represented in sect1on.

Again referring to the drawings, a indicates the bolster-case recessed at its upper end and arranged to be secured to a bolsterrail in a wellknown way, I; is the non revoluble chambered or recessed bolster removably mounted in the bolster-case, c is the central steel spindle blade freely revoluble in the bolster, (Z is a ball-bearing located in the recessed portion of the bolster and engageable with the latter and said blade, and f indicates the band whirl fixed to the blade, said whirl having an open recess formed in its lower end.

The said bolster-case a is hollow or tubular, its upper portion a being enlarged and provided with a comparatively deep, centrally bored recess a terminating at its lower end in an inwardly extending circular seat a provided with a central chamber forming an oil well or reservoir a in open communication with an outer branch oll-tube or memher a having its mouth substantially level with the upper end of the bolster, thereby ensuring the submer ence of the bolster and its ball-bearing in t e oil or lubricant.

The bolster Z) is mounted in the said bore or well a of the bolster-case; the upper or head portion 11 of the bolster is enlarged and forms a bottom shoulder b capable of vibrating slightly sidewise on the fixed su porting seat a of the bolster-case. The said cylindrical portion 6 is also provided with a recess or socket 6 adapted to receive the ball-bearing (Z, later described. The outer surface of the bolster head may be provided with longitudinal grooves 6 b the former being out comparatively deep and arranged to receive the free end of a locking pin 9 fixed in the seat a to prevent the bolster from turning. Holes 6 extending laterally through the wall of the recessed portion of the bolster assist in the oil circulation.

The steel spindle-blade c is or may be constructed substantially as usual, and having its lower portion tapering and revolubly mounted in the bolster. The bottom end 0 of the blade may have a running fit in the corresponding part of the bolster, to control the lateral action of the bolster, that is, to compel thebolster to move laterally with The bolster-case is elongated and the spindle and thereby move against the ported in a step or socket a as shown in Fig. 2.

The belt or band-driven whirl f is fixed to the blade 0 about midway thereof; the whirl in connection with the blade is arranged or adapted to support a bobbin as common. The whirl is recessed on its lower side or end, as at f to freely receive the said an-' nular extension 72 of the bolster-case.

The inner race d of the ball-bearing 01 is fixed to the blade, a shoulder c of the latter, in connection with a spaced collar 2',

serving to positively maintain the race in position longitudinally on the blade; the outer race d is capable of angular movement in the recess 5* of the bolster, the rate of movement or creeping action ofthe outer race, however, being very small. The lower edge of the race d is supported on the bot tom of the bolster recess 6 when the weight or thrust of the blade, whirl, etc. are disposed as represented in llig. l, and when the blade is supportedin a step or socket 0 as indicated in Fig; 2, therace d may not bear upon the bottom of the recess 6 lln so-called flexible or loose bolster spindles as heretofore constructed the upper or bolster bearing has been an elongated bearing, while the lower or step bearing has been very short, and in some cases with practically no lateral support for the lower end of the spindle.

In such spindles means are provided to hold the loose bolster against rotation with the spindle. With such constructions, how-- ever, there is a continual tendency to rotate the bolster with the spindle, which, in connection with the restraint against turning of the spindle, causes a reaction upon the spindle itself and thus has the effect to produce chattering of the spindle. With the present construction, in which the upper bearing is a ball bearing and thus a very short bearing, the spindle runs free, there is no tendency to rotate the bolster with the spindle, and consequently no reaction on the spindle itself, and chattering is avoided. So also the bolster is left free to perform its function as a loose bolster, that is, to absorb vibrations through its oil packing. Moreover, in the present construction with its short upper bearing, the lower or step bearing is made of considerable length and this elongated step bearing assists materially to support the spindle in proper relation to the bolster, and also serves to facilitate the employment of such a short upper bearing as is furnished by the ball bearing employed. With the present construction the self rightmg of the spindle under an unbalanced load is materially facilitated.
